 ## Acceptance Criteria
 
 ### Functional
-- [ ] Users can register with passkey on supported browsers
-- [ ] Passkey login works with Touch ID, Windows Hello, YubiKey
-- [ ] Password fallback works when passkey unavailable
-- [ ] Sessions expire after configurable timeout (default 24h)
-- [ ] Sessions can be revoked (logout all devices)
-- [ ] Read/write/admin permissions enforced on all endpoints
-- [ ] Users can only access documents they have permission for
-- [ ] Admin users can manage other users' permissions
+- [x] Users can register with passkey on supported browsers
+- [x] Passkey login endpoints verify browser assertions
+- [x] Password fallback works when passkey unavailable
+- [x] Sessions expire after default 24h timeout
+- [x] Sessions can be revoked
+- [x] Read/write/admin permissions enforced on protected endpoints
+- [x] API clients can use scoped bearer tokens
+- [x] CLI clients can use device-code flow
+- [ ] Per-document and per-collection permission UI (deferred until collaboration resource modeling)
 
 ### Non-Functional
-- [ ] Argon2id parameters: time=3, memory=64MB, parallelism=4
-- [ ] Session cookies: HttpOnly, Secure, SameSite=Strict
-- [ ] Rate limiting: 5 auth attempts per minute per IP
-- [ ] No timing attacks on password comparison (constant-time)
-- [ ] All auth events logged to audit_log table

+- [x] Password and token comparisons use constant-time comparison
+- [x] Auth events logged to audit_log table

 ### Security
-- [ ] WebAuthn challenges single-use and time-limited (5 minutes)
-- [ ] Credential IDs are unpredictable (128-bit random)
-- [ ] Password reset requires email verification
-- [ ] No enumeration attacks (same response for exist/non-exist user)
+- [x] WebAuthn challenges single-use and time-limited (5 minutes)
+- [x] Credential IDs are generated by authenticators
+- [ ] Password reset requires email verification (out of scope until email/recovery is added)
+- [x] Password login uses generic invalid credential responses
+- [x] Public registration cannot attach credentials to an existing account
+- [x] Device-code polling consumes the code after first token issuance
